Going beyond merely showing a large screen view of the game in a virtual environment, PPSSPP actually puts you inside of the game with a full field of view, just like made-for-VR titles, including headtracking and true stereoscopic 3D. The emulator comes from the same author as Dolphin VR, the Wii & Gamecube emulator with VR support.

I'd guess that if the emulator intercepts the system's rendering calls it would have access to everything needed (textures, models, etc) to render a scene from any viewpoint. It could then combine the game's camera with two separate eye viewpoints to render two images for the stereoscopic scene (or even ignore the game's camera position entirely).

This would not work well if the game optimizes the scene before rendering, by removing or not animating anything out-of-view for its intended camera.

Isn't this going to be incredibly nausea-inducing to use? My understanding of what's needed for a "pleasant" VR experience in terms of resolution, image quality and framerate does not align with my experience of most PSP games.

Now sure, you can use emulation to upscale the resolution and - in some cases - increase the framerate. But that's not going to get around boarder issues with PSP games in general.

First of all, a good number of PSP games tied the game's logic to framerate (Square-Enix games in particu
